we have done register admin page, login page, view attendance history and read card.

This week we get to start our library attendance project but first we need to download the sample code using CEPA EZ-Link Card Reader into our laptop and test run so as to avoid any unnecessary during our start of project. The sample program that we download allow us to read the card and store its card ID into the database and recognize it whenever we tap the card onto the card reader.

We divide our project tasks in the following:

Suqiang:database, finalization, report
ChongHoe:coding, report, database
Me:coding, report, finalization
Pearllyn:interface design, coding, report

This week we had our assignment 2 presentation. We were given some topic to start with, and we decided to focus on
1.benefit of RFID
2.social impact of using RFID
3.the future of Singapore be with RFID

Through the research,i found that RFID is very useful and can assist us in any other ways.For example,RFID can help to reduce administrative error, labor costs associated with scanning bar codes, internal theft, error in shipping goods as well as increase sales and guarantee traceability.

For the social impart of using RFID, we had the positive impart and the negative impart. The positive impart will be, it can speed up daily activities where RFID moves faster than retailers publically admit as right-time retailing is growing. As for the negative impart, it had tendency to cause theft of information and inadequate encryption. Furthermore it intrude user privacy where inappropriate use of personal data and people could be unknowingly tracked by the RFID transponders.

Amazingly,there is lots of thing we could be done in the future using RIFD. One of the example will be, RFID on Spectacles. Many of us will encounter when one need to wear spectacle, optometrists will use phoroptor for sight testing, to measure an individual's refractive error and determine his or her eyeglass prescription. With the aid of RFID tag on our spectacles, we doesn't have to go through sight testing to determine our eyesight degree. So just scan the RFID tag on our spectacles to the reader, we can determine each individual degree and it time saving!Conclusion, RFID rapidly evolving technology and it could be used for surveillance purposes but
has the capacity to be abused.

This week we had our TOR presentation, and my grp consists of pearllyn, chonghoe and suqiang. The topic given to us was lift simulation or attendance system, we had to choose either one of them to focus on. We chose attendance system and we will be touching on library attendance system.

Library uses designated computers for their staff to clock in and out. The increasing of staff add to the number of people login to the computer leading to congested network jams.
Thus, we have decided to create a system with the to avoid computer hanging and wasting precious time when staffs clock in and out. (We assume that library's staff uses computers to clock in and out instead of RFID)




Our project objectives is to:

• Clearly display relevant information (e.g. time)
• Record real time data and pass it to processing system to maintain a log
• Comprehensive, effective and efficient system
• Automating the staff administration

Our system feature includes

• Check lateness
• Unauthorized staff entering the room
• Accumulate hours of overtime
• Attendance weightage calculations
• Display no. of annual leave they left
• Email notification for lateness
• Confirmation of message sound will be heard when they tap e card
• Calculate extra pay for public holiday
• Check if one is helping another to tap card
• Picture profile recongnization
• Web-based

How its work

1. A monitor and a card reader will be placed next to each other.
2. On the monitor screen, it will show the web page with the login page.
3. The staff will have to tap their staff cards onto the card reader for authentication to the library and for attendance taking purposes.
4. After they have tapped their staff cards against the card reader, the system will automatically check with the database for existing ID.
5. If the staff are late, the system will display the font in red.
6. Confirmation of message sound will be heard when they tap e card
7. Attendance taking via this method will prevent any "unauthorized" staff from access to the library staff room.
8. And since each staff card has its own unique ID, it will check against the database to retrieve their details (i.e. the number of times they are absent).
9. After the staff have tapped their card, the system will automatically calculate their annual leave left and display on the screen.
10. The system will also check against its database to retrieve information on their attendance status.
11. When the staff come late for number times, an email notification will be sent to him/her informing about it.
    

This week we had our practical on friday .We will be using Ekahau's Wi-Fi based real time location system(RTLS). The Ekahau Real-Time Location System is a wireless radio frequency solution that continually monitors and reports real-time locations of tracked resources.

Unlike competing solutions which are based on Time Difference of Arrival (TDOA) technology, Bluetooth or active RFID, and therefore require deployment of costly RF- antennas or receivers, Ekahau's patented RF modelling technology leverages standard Wi-Fi access points, so no proprietary infrastructure is needed.

By using standard 802.11 access points and Wi-Fi tags, any Wi-Fi network can now work as the backbone and sensor network for a real-time location system. This quickly translates into faster deployment and improved cost-effectiveness.




Tools for the lab:

Ekahau Tag

These tags operate independently, report signal strength measurements, provide 2-way communication for interfacing with application and tag management.
____________________________________________________
Ekahau Software client- "The software tag"


Laptops, PDAs, Tablet PCs, wireless barcode scanners and other mobile devices can all be accurately tracked in real-time using Ekahau Client software. The software installs into computers and sends signal strength measurements in the background to the Ekahau Positioning Engine.

Notebook with Ekahau Site Survey and wireless card.



To get a clear view of what is going on in our network, users must perform a site survey around the network. With Ekahau Site Survey, all that’s required is a quick walk around the area in order to detect all the 802.11 access points in the network. And if a few spots are missed, Ekahau Site Survey can accurately fill in those spots to minimize the workload and maximize accuracy.

2.Perform surveys and tracking
3.Display asset locations
4.Using Ekahau vision

Mr cheng also asked us to find out the new ez-link card reader for the new ez-link. I managed to find the new ez-link card reader which is the ACR122U.




The ACR122 is a PC-linked Contactless Smart Card Reader/Writer developed on the 13.56MHz Contactless (RFID) Technology and followed the ISO/IEC18092 Standard for Near Field Communication (NFC), supporting not only Mifare®, ISO 14443 A and B cards but also NFC and FeliCa contactless technologies.

The ACR122 is a USB Plug and Play device with the CCID compliance. It is ideal for both secure personal identity verification and online micro-payment transactions. Typical applications of the ACR122 reader include access control, e-payment, e-ticketing for events and mass transit, toll road fare collection and network authentication.

Price: EUR44.00

i'm not sure whether what i found is correct =(

This week we had our 3rd practical. The objective of this practical is to learn how to implement an Access Control System using RFID and program the movement of the access system for a lift. An access control system is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. It is generally seen as the second layer in the security of a physical structure.
So our task for this practical is to write software to fulfill the requirements of the card access system for the lift. Our tools for the practical will be using eclipse, Felica cards and Sony Pasori Reader and lift teaching kit. First we will write the code to get the input from the lift and modify the code whereby it's able to detect all the six buttons. Next write the code to control the lights in lift whereby switching on the light when the button being pressed by user. Next, to write code that is able to read the card's ID. Lastly will be to be able to move the lift when the floor's button is pressed and upon reaching, it will switch off the lights.
Sony Pasori Reader

Felica card


My reflection:i learnt how to getID number from the Felica card and write my own application to read the card's ID and able to control the lift. In addition, EZlink card can also use by using Sony Pasori Reader Felica SDK.

This week we had our presentation on thursday and practical on friday. The question for our presentation will be how logistics industry benefit from RFID technology and give example of RFID applications in the logistic industry. One of the example will be IBM in USA, how they benefit from RFID. Next we will choose our own topic regarding of RFID. Our grp will be touching on the healthcare, basically RFID in hospital. Examples of RFID in hospital are RFID patient tracking, RIFD tags for dressing in KK women and children hospital and using RFID to take patient temperatures.Mr cheng commented that our slides is interesting.

During our practical, what we had learnt is that to use RFID technology to track outdoor assets like cars in the carpark lot.And learnt how to use Time Difference of Arrival (TDOA) algorithm to determine the location of the outdoor assets.

RFID vechicle parking positioning system

• control up to 4 entrance/exit per reader
• tag can be read through winshield with metal film
• Various interface options between Reader & PC via WiFi, Bluetooth, USB, RS232
  

I learnt that wireless signal is transmitted at a regular interval by the Active RFID tag in the vehicle.Active tags have an internal battery to power them and are usually RW (tag data can be rewritten and/or modified). And its generally can transmit their data over a longer distance, the tag itself is larger than a passive tag, and has a limited operational lifespan.

There are 3 ways ways of describing an asset location:

• Real-time location: able to track car within the area in the map
• Presence: whether the car still inside the carpark lot
• Choke-point: to detect if the car leave the carpark lot

The equipment we used for the practical:

1.1Tag 1.2 Button tag(another type of tag)

Tag is a microchip combined with an antenna in a compact package; the packaging is structured to allow the RFID tag to be attached to an object to be tracked

__________________________________________________________________


2.Tag Activator

Tag Activator is a hardware component that connects tags wirelessly to the tag manager workstation, and transmits programming information to the tags.

________________________________________________________________

3.Exciter


The Exciter triggers AeroScout’s tags as they pass through a choke point to transmit a message that is received by a standard Wi-Fi Access Point or AeroScout Location Receiver.


_________________________________________________________________
4.Location Receiver


AeroScout location receivers provide robust and sophisticated location measurement capabilities packaged in small, easy to install devices designed for harsh conditions. The location receiver receives transmissions and executes sophisticated radio signal measurements and calculations that are sent to the AeroScout Engine software.
